With
the rapid development of Internet technology and the rapid migration of
Internet users on social platforms, the invisible gap between the public opinion
field at home and abroad is becoming thinner.

The
emergence of network media to traditional news information industry reform of
modes of production, distribution way, operation opportunity, and social media
in The information and news spread, exchange and sharing, we once again
highlight The advantages of "The Internet is time press media," The
fact that The status quo. When interpersonal communication, group communication
and mass communication occur on the same platform, the communication mode of
information also changes from "media-audience" relationship to
"social" relationship.

According
to the survey, one third of Americans get news through Facebook, and 80 percent
of them share news through friends. According to the American press
association, young people are used to getting news through social media such as
Facebook and Twitter, and less through professional media such as news
websites, television or newspapers. When major emergencies occur, the news
timeliness advantage of social platforms makes them get more attention and even
become a news source of professional media. Twitter, a former vice President
Kevin sauri even claims that Twitter is, in fact, and it is not a social media
news media. In the case of the kunming railway station terrorist attack, the
Malaysia airlines crash, the Boston bombings and the stampede on the bund,
social media platforms posted information and attracted public attention faster
than professional media organizations.

The
status and function of the Internet era, the traditional information producers
to millions of Internet users, social media users not only the passive
information receiver, more as information producers, the organizer, the
multiple identities of the bearer. Common network users can through social media
release fresh stories on the Internet, can be based on personal preferences and
to spread the existing information, also can be in handling, translated others
published information between different platforms.

Both
at home and abroad in the process of network public opinion field information
cross-domain circulation, social media users to assume the role of the bearer
of the individual and group created different social platform, communication
barriers between geographical areas, cultural environment, the occurrence,
development and results of Internet public opinion events have the effect that
cannot ignore. The information source also extends from professional news
organizations to we media, citizen journalists and ordinary netizens. Private
channels have become an important component of information exchange at home and
abroad, while non-institutional sources have played an important role in
promoting information exchange.

Content
type, network public opinion field at home and abroad there are entertainment
trends: on the one hand, serious information content declined, entertainment
gossip, TV shows, sports events and other topics attention far beyond politics,
society, people's livelihood and so on serious topics; On the other hand, the
content of news information pursues drama, stimulation and timeliness, which
makes the public opinion environment more complex while increasing the
readability of the information obtained by network users.

Network
and the lack of information production and communication process of the social
platform "gatekeeper" role, information source, the content and the
details of true and false confusion and flaws, social media has become a
hotspot of rumors and false news, also make the proportion of authoritative
information channels. Nowadays, the Internet is not only the main channel for
ordinary netizens to get information, but also an important information source
for professional news media. As professional media will network platform to
false information without turning into "news", reported through the
formal channels, reproduced, can only be the result of the false information of
negative effect to expand, the credibility of media, the official authority.

There
is no doubt that American Internet companies dominate the global market of
social media. According to statistics, of the 18 social network platforms with
more than 10 million monthly active users worldwide as of March 2015, 10 are
from the United States, accounting for 55% of the total. China, Russia and
Japan are among online social media, but its social network from a number of
users and recognition abroad, international market share still lags behind that
of the products in the United States, only in the domestic market leading
position.

China
leads the world in the number of active Internet users and the penetration rate
of social media. However, mainland China has no consistent users contributing
to overseas social media. A more typical example is the social media giant
Facebook, which has achieved some success in every market in Asia except China,
but its penetration rate in mainland China is not large.

Internet
products often develop and formulate corresponding platform functions according
to the cultural background of the target users, and the public opinion field
formed on the platform is also different. Such as interpersonal communication
in the western society pay attention to safety distance, emphasize individual
privacy, users on the basis of offline relationships distinguishes the
difference choice E-mail, private number or different social tools such as
social media accounts.

Overseas
social media as a whole have no requirements on the real-name system of user
accounts. Internet anonymity has obvious characteristics, and Internet users
are more motivated to participate in public topics and public opinion
supervision. The functions of domestic social media platforms are more
diversified, and they keep enriching functions to meet users' needs while
retaining their own characteristics.

The
public opinion of Twitter and sina weibo properties than the letters and
WhatsApp is more obvious and prominent, is meet the demand of grassroots
Internet voice public opinion space and platform of public opinion direction
from professional media guide track hot topic for the user. Hot topic in the
two platforms set list, participate in the user type, subject labels Settings
are emphasized its since the media attribute, make public opinion participants
track hot topics and participate in the debate has become more convenient.
WhatsApp and micro letter more attention based on the strong relationship
between interpersonal communication, especially in the first set of functions,
meet the demand of user's communication, only not to provide users with
participation and discussion of public affairs.

One
of Twitter's most distinctive attributes is the topic tag, which categorizes
and aggregates platform information through user-created topic tags. Topic tags
will not only allow users to easily find a specific topic to join them, also
improve the feasibility of tracking platform on public opinion, it makes the
tens of thousands of people in a very short period of time focusing on the same
topic, evolution to influence the behavior of real activity. Some of the
biggest international events have the power of Twitter hashtags, such as the
earthquake in Haiti, the hunt for osama bin laden and the 2012 U.S. election.

At
present, topic tags have become an essential function of almost all social
media on the Internet. Sina weibo, Facebook, Instagram and others all have some
form of topic tags. Sina weibo also expands the activity function and hot event
page on the basis of the topic tag, further increasing the public opinion heat
and communication effect of the topic

Sports
topic on Twitter platform awareness ahead, topics include domestic major events
such as the NFL, NBA, Super Bowl and so on, have the world famous game such as
wimbledon tennis championships, World Cup, etc. In the 2014 super bowl, for
example, Twitter officially counted 24.9 million tweets during the game, with a
peak of 380,000 per minute, not including retweets and comments.

Political
and livelihood issues ranked second, including the Indian election, the us
election, and the 25th anniversary of the fall of the Berlin wall. Specifically,
although the hot topics on Twitter come from all over the world, most of them
are around European and American countries or are based on western mainstream
culture.

Weibo
hot topic type, by contrast, are characterized by entertainment: 2014 referring
to the highest degree of 30 hot topic, with most TV shows, social news and
sports event types. Variety shows and popular TV series occupied the vast
majority of the microblogging hot topic, variety show "dad where to
go" "I'm a singer" "Chinese good voice" topics into
the top 10, and other hot topics include "gala" smog
"horse" "" "iPhone6 "and so on.

The
convenience of the Internet and timeliness also accelerated the spread of bad
information, anonymity makes bad information in the online world publishers, visitor
and disseminator difficulty identifying and tracing, brought difficult to crack
down on Internet bad information. According to the report, "etim terrorist
organizations" in recent years, through the network channels to domestic
transmission with fear of audio, video, and the number and frequency rises year
by year: 2010 8, 13, 2011, 2012, 32, 109 units in 2014. The transformation from
the smuggling of religious propaganda into China in reality to the transmission
of violent and terrorist audio video online has greatly increased the
difficulty and necessity of combating crime.

Compared
with the events in the public opinion field at home and abroad in recent years,
the fermentation speed and the cross-border communication speed have been
rapidly improved. It took less than 24 hours for the topic of "platinum
blue and black skirt" to be introduced into the domestic social network,
and only 3 hours from the introduction to the detonation of the topic in the
domestic public opinion field. In the case of "brother orange", the
average response speed of Internet public opinion communication at home and
abroad was only 6 hours, half the time difference between China and the United
States. This has undoubtedly increased the difficulty of information management
for the domestic network opinion platform, and posed a test for the stability
of the platform infrastructure.

A
lot of information of cross-border transmission is put forward for the Chinese
Internet inquiries, the new situation, traditional management network public
opinion has been unable to meet demand and to be closer to the overseas
netizens way into overseas network public opinion field actively, strengthen
the joint, expand the overseas influence of Chinese public opinion.
